Blue-billed CurassowCrax alberti

As befits its name, this large curassow is the only one of its genus to sport blue adornments to the bill. Males are black with a white vent and tail tip to tail, a horn-colored bill with a fleshy blue cere and a hanging wattle. In contrast, females are also black but have black-and-white crest feathers, fine white barring over the wings and tail (and in the barred morph also on the breast and belly), a rufous lower belly and undertail, and a bluish base to the bill. The Blue-billed Curassow is endemic to northern Colombia, where its populations are now highly fragmented and usually tiny, although an active conservation program is attempting to redress this. BirdLife International currently considers the species to be Critically Endangered.
